The subject matter of the inventionisa. magneto-electric machine intended. for example to beused for pocket lamps, for lighting cycles and for other applications.

armature comprises two C-shaped parts arranged in the shape of a cross, in such a manner that their extreme branches are-opposite each other, and are connected by a 10 central part carrying the winding formed by one single coil.

The accompanying drawings show, by way of example, a constructional form of the magneto-electric machine as applied to a pocket lamp.

Figure l'is a plan view partly in section on line II, Figure 2.

Figure 2 is a sectional elevation of the machine.

The stationary armature of this constructional form comprises two parts ab-c, def, made of magnetic materiahhaving the shape of a C and having branches b-e which are fiat and central in position and also extreme branches a and a mounted in the arc of a circle of the same radius. They are placed crosswise and are connected by a central tubular part g of magnetic material, in such a way that their extreme branches, are opposite each other and the central part 9; the four branches forming a sort of cage. Upon this central part 9 there is, situated the armature winding composed of a single coil h of circular form one of the ends of which is connected at the base of the lamp and the other. one of which is insulated therefrom.

In the central part g .there located a socket'z' of non-magnetic material, for ex- 40 ample, brass, one of the ends of which is of relatively small diameter and screwed into an opening in the jacket or casing 9' of the lamp, beyond which it is provided with a nut 70; the other end of the socket .z' carries afiange '0 bearing upon the part d -ef;

in this way this socket 11 keeps assembled the parts ab-0, d ef, g and fastens the armature to the jacket 9'.

The shaft Z ofthe rotary inductor turns in thesocket i and also in an opening m n the jacket j and receives its movementifrom a gear wheel n keyed upon it. It carrles a non-magnetic cylindrical sheath 0, of brass for example, against the lower surface of It is characterized by the fact that "its maenn'ro-nnnc'rnrc MACHINE.

which four magnets p-gr-s arranged in 5 a quarter of a circle are connected in their central parts thereto by screws t and nuts u.

If it be assumed that the two poles opposite the magnets p and g are north poles and that they move opposite the branch (Z of 50 I the part d-ef' in course of rotation of the armature, it will be seen that theymagnetic flux leaving these poles passes into the branches de, into the central part g, into the branches b--0 or ba so as to'abut on the south poles of the magnets p-g-r-s.

It will also be seen from an examination of the figures that the construction and mounting of the armature and of the inductor are very simple; there is only one single coil 72. of circular form which is easy to make mechanically; the manufacture of the parts abc, def can'be easily effected by stamping and that of-the part 9 by a stripping operation; the socket 2', at the same time, holds these three parts assembled, fastens them to the jacket 7' and renders the said coil in motionless.

The central part g could during manufacture be cast together with one or the other .0 of the parts ab-c or zlef; the assembly of the three parts could take place in a manner other than that described.

Instead of being stationary, the armature of the machine may be moveable.

The magneto-electric machine can be given applications other than those which have been set forth.

We claim: s

1. In a magneto electirc machine, a stationary armature comprising oppositely disposed si'de members spaced at right angles to each other and each having ends arranged in a circle, a single armature winding in the space formed by the parts of the armature, .95

a centrally disposed member'having a hearing therein and a flange at one end thereof, a nut turned down on the screw threaded opposite end of the centrally disposed member: for connecting the parts ofthe said no armature, a shaft journaled in the bearin v in the said centrally disposed member, an rotary magnets mounted on the shaft and adapted to revolve e'xteriorly of the ends of the side members of the armature.

' 2. In a magneto electric machine, a Sta-'7 tionary armature comprising oppositely disposed side members spaced at right angles space within the parts ofthe armature, a

to each other and each having ends arranged in a circle, a sin le armature winding in the space formed y the parts of the armature, acentrally disposed member hav in a bearing therein and a flange at one-end :posed slde members. spaced at right anglesthereof, a nut turneddown on the screwthreaded opposite end of the centrally disposed member for connecting the parts of the said armature, a shaft journaled in the bearing in the said ,"centrally disposed'memher, a sheath connected to the said shaft, and a plurality of magnets connected to the 'nsaid sheath and adapted to revolve exterior- 1y of the ends of the armature. v

'3. In amagnetq electric machine, a staside-membets of the tionary armature comprising'oppositely disposed side members spaced at right angles to each other and each having ends arranged ina circle, a single armature winding in the casing,a member centrally disposed relatively to the parts of the armature, means' coacting with said centrally disposed menr- -ber for simultaneously connecting the parts of the armature to each other and to the casing, a shaft journaled in the'said centrally disposed member, and a plurali of magnets carried by the said shaft an adapted A 4. In a magneto-electric machine, a stationary armature comprising oppositely disto each other and each having'ends arranged in a circle, a single armature winding in the space'within the parts of the armature,- a casing, a centrally disposed member passmg 7 through the side members of the armature and having a flange at one end bearing against one side member of the armature, the 0pposite end of the centrally disposed member a parts of the armature together and fix them I in position relatively to the casing, a shaft journaled in the said centrally disposed member and also in the casing, a sheath fixed to the said shaft, anda plurality of magnets carried by the said sheath and adapted, to

revolve exteriorly of the ends of the side,

members of the said armature.

In testimony whereof we aflix our signatures.
